Answer 1

plasma membrane

I think

Answer 2

The layer of the bacterial cell that helps them against water and nutrient loss is:

b) plasma membrane

• The cell envelope has three main parts that are the cell wall, the middle lamella, and the secondary cell wall. The cell wall guards from any germs to enter inside the cell. The slime layer of the bacterium cell is usually very thin and can be washed off very easily.
• The plasma membrane of the cell or the cytoplasmic cell membrane is the most important layer of a bacterium cell as it does not allow any cell content to move out and it also regulates the entry of the nutrients into the cell and prevents water loss. The plasma membrane also maintains a barrier between the outside and inner contents of the cell.
